hijacked his own big fight press conference by jumping on to the stage early, grabbing a microphone and ordering his promoters and opponent to join him.
German heavyweight Tom Schwarz, who he fights in the MGM Grand Garden on his Vegas debut on Saturday night, as well as Bob Arum and Frank Warren obliged.
Fury was dressed in a small-checked suit of many colours, each square picturing bare-knuckle champions over more than a century of the traveller history.
He greeted Schwarz with an enthusiastic embrace.
He wound up roars from his and Schwarz's teams and fielded random questions before the TV transmission started.
Arum and Warren chorused: 'He sells the fight for us with his charisma.' As the cameras hurriedly began rolling Fury launched into a rendition of Rag'n'Bone Man's hit single 'Human'
That led him into his personal promotion as a depression survivor.
'Me and Tom are here to kick ass,' he said.
'But my real calling card for this fight is to help other people, to inspire them not to give up.'
Fury's much publicised recovery from near-suicidal depression has struck a chord with well-wishers of all nationalities on the famous Strip.
He says: 'I'm humbled by all the attention.'
"You're a good looking chappy! Sorry for my German.""Shall we sing a song, Tom?!" ??"Who has the minerals to get up here and give us a song?" ??Tyson Fury and Tom Schwarz met on stage for the first time and they're now best mates ?? #FurySchwarz
